switch the xbox off and if you have any hard drive etc connected to the xbox or usb devices disconnect them
, then switch it back on while holding the sync button, the one you press to pair the controllers with , hold that for 30 seconds and then release it, see if it will show up on the tv. If it still wont show anything on the screen , check all cables, borrow one that you know is working to try on it. if that doesnt work try another power supply. The best way to test it though is to take it to a friends and unplug there xbox and use their leads and power supply to see if yours boots up. Another check you can do is hold the sync button in and press the eject button , if an error is happening the ring of lights will change , you need to press eject 4 times, without letting go of the sync button, each time you press it the red lights will come on, code is as follows

are you using HDMI input? Make sure you have it on the correct input as it will not start until it sees the the input from your tv. don't switch inputs real quick, give it some time and it should boot(about 3-5 seconds). Mine did the same thing with HDMI only.

Note 1 If a saved game file is corrupted, it can produce a disc error message in that game, particularly when the game starts. You can resolve this issue by deleting all saved game files for the affected game from the Xbox hard disk. This method is effective approximately twenty-five percent of the time. If you experience this disc error message with more than two games, this procedure will likely not resolve the issue.

Note 2 Do not use laser lens cleaners, or similar products. Microsoft has not determined the effectiveness of these products or the affect they may have on the Xbox system. Microsoft cannot promote or recommend any type of laser lens cleaner for use with the Xbox system.

Have you re-connected the sata cable the correct way round,if you put it upside down you will have problems, connect it the other way around and see if it works.
It sounds like your console was suffering from screen freeze, if it would not respond to your controller commands, the best thing to do to cure this is to replace the heatsink paste on top of the gpu(under the small heatsink) then repace the clamp by screwing the heatsink to the board, this is basically the same cure for rrod, so there are plenty of guides around.
